Aurora Interface and Diagnostics (AID) Tool
The Aurora Interface and
Diagnostics (AID) Tool is a
device that is a member of
the Aurora network. The AID
Tool is used to troubleshoot
equipment which uses the
Aurora control via Modbus
RTU communication. The AID
Tool provides diagnostics,
fault management,
ECM setup, and system
configuration capabilities to the Aurora family of controls. An AID
Tool is recommended, although not required, for ECM airflow
settings. The AID Tool simply plugs into the exterior of the cabinet
in the AID Tool port.
